Embodiment Construction

[0052] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying illustrative drawings. When designating elements in the drawings with reference numerals, the same elements will be denoted by the same reference numerals even if they are shown in different drawings. Also, in the following description of the present disclosure, when a detailed description of known functions and configurations incorporated herein would make the subject matter of the present disclosure rather unclear, the detailed description will be omitted.

[0053] Also, terms such as first, second, A, B, (a), (b), etc. may be used herein when describing components of the present disclosure. Each of these terms is not used to define the nature, order or sequence of the corresponding component, but is only used to distinguish the corresponding component from other components. Where it is described that a structural element is "connected to", "coupled to" o...

Abstract

The present disclosure relates to a touch circuit, a touch sensing device, and a touch sensing method. According to the present disclosure, it is possible to obtain an accurate touch sensing result (the presence or absence of a touch and / or a touch position) by compensating for the unintentional change in the quantity of the charge corresponding to a signal obtained by driving a touch screen panel, so as to obtain sensing data in which the influence of the parasitic capacitance generated inside or outside the touch screen panel is reduced or eliminated, thereby improving capacitance-based touch sensing performance.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to a touch circuit, a touch sensing device, and a touch sensing method. Background technique [0002] With the advent of the information age, display devices for displaying images are increasingly required to take various forms, and in recent years, devices such as liquid crystal displays (LCDs), plasma display panels (PDPs) and organic light-emitting display devices ( Various display devices such as OLED). [0003] Among these display devices, there are touch display devices capable of providing a touch-based input method that enables a user to easily or intuitively input information or commands in addition to conventional input methods using buttons, keyboards, mice, and the like. [0004] In order to provide a touch-based input method, this touch display device includes a touch sensing device capable of recognizing whether a user is performing a touch and accurately detectin...
